Call to undefined function: _block_rehash() in /profiles/cod/modules/og/og.install on line 89

I'm trying to use the COD installation profile and received several errors on the install page before I do anything. If I continue with the install and select the COD profile I finally receive the following error:

Call to undefined function: _block_rehash() in /profiles/cod/modules/og/og.install on line 89

This happens when I try to install using the COD Profile Installation following the instructions in the README.TXT.

I'm using the code.profile size 67,369 dated 11/5/2007, 3:39 PM.

I also receive the following errors when I first try to launch the Drupal install:

Notice: Undefined index: profile in /install.php on line 399

If I run the Drupal install without the cod directory in the profile directory, then the install works fine.

My PHP Version 4.3.9. I can upgrade to 5.0, but was hoping to not have to do that as my client currently only has 4.4.1 installed.
